The word 改正 (gǎizhèng) is a compound verb formed by combining two characters with related meanings: 改 (gǎi), meaning "to change" or "to alter," and 正 (zhèng), meaning "correct" or "upright." In this construction, 改 acts as the action, indicating a process of change, while 正 specifies the purpose or direction of that change—towards correctness. Thus, the combined meaning is "to correct" or "to amend," where one makes alterations specifically to set something right. This follows a common pattern in Chinese where verb-verb or verb-adjective compounds create a resultative meaning, with the second element often indicating the result of the first action.
